RESUMEN

BACKGROUND: Although immunocompromised patients have a higher risk of developing cutaneous squamous cell carcinomas, it is unknown whether immune status is an independent risk factor for poor outcomes. OBJECTIVE: To compare cutaneous squamous cell carcinoma outcomes in immunocompromised and immunocompetent patients when controlling for T-stage. METHODS: We performed a retrospective cohort study at 2 tertiary care centers, examining 989 primary tumors from 814 immunocompromised patients (solid organ transplant: 259 [31.7%], chronic lymphocytic leukemia: 113 [13.9%]) and 6608 tumors from 4198 immunocompetent patients. Our primary outcome was the composite of disease-specific death or tumor metastasis ("poor outcomes"). RESULTS: Immunocompromised patients had 50% more high T-stage tumors (ie, Brigham and Women's Hospital stage T2b and T3), than immunocompetent patients (3.3% vs 4.9%, respectively; P < .001). Significant predictors of poor outcomes included tumor stage (sub hazards ratio [SHR], 14.8 for high T-stage tumors; 95% confidence interval [CI], 8.0-27.6; P < .001) and male sex (SHR, 2.3; 95% CI, 1.4-3.8; P = .002). Immune status was not a significant predictor (SHR, 1.04; 95% CI, 0.69-1.6; P = .85). LIMITATIONS: This study is retrospective. CONCLUSION: Although immunocompromised patients had 50% more high T-stage tumors than immunocompetent patients, immunocompromised patients had a similar chance of metastasis and disease-specific death when adjusting for T-stage in our cohort of primary tumors.

RESUMEN

BACKGROUND: Calciphylaxis is a rare disorder characterized by skin necrosis caused by calcium deposition within vessels, thrombosis, and subsequent tissue ischemia. Penile involvement may rarely occur. OBJECTIVE: To identify risk factors, diagnosis, management, and mortality of patients with penile calciphylaxis. METHODS: A retrospective medical record review was conducted of 16 patients with penile calciphylaxis treated at 2 large urban tertiary care centers between January 2001 and December 2019. A control group of 44 male patients with nonpenile calciphylaxis at the same institution was included. RESULTS: The median survival of patients with penile calciphylaxis was 3.8 months (interquartile range, 27.0 months). Mortality was 50% at 3 months and 62.5% at 6 months for penile calciphylaxis, and 13.6% at 3 months and 29.5% at 6 months for controls (P = .008). Patients with penile calciphylaxis were less likely to be obese (P = .04) but more likely to have hyperparathyroidism (P = .0003) and end-stage renal disease (P = .049). LIMITATIONS: Retrospective study design and small sample size. CONCLUSIONS: This study further defines the disease course of penile calciphylaxis, which has high mortality. Imaging may be used to aid diagnosis. Risk factors include end-stage renal disease, hyperparathyroidism, and normal body mass index.

RESUMEN

BACKGROUND: The National Comprehensive Cancer Network (NCCN) has established guidelines for the treatment of keratinocyte carcinomas (KCs). Complete circumferential peripheral and deep margin assessment (CCPDMA) is recommended for "high-risk" tumors that cannot be closed primarily. If flap or grafts are needed and CCPDMA was not used, it is recommended that reconstruction be delayed until achieving clear margins. OBJECTIVE: To measure provider utilization rates of the NCCN guidelines for high-risk KCs and assess barriers that are limiting adherence. MATERIALS AND METHODS: A ten-item questionnaire was distributed to NCCN nonmelanoma skin cancer panel members and physicians participating in KC treatment at academic institutions. RESULTS: Response rate was 49% (57/116). Responses were categorized by practice area: Mohs surgery, pathology, and other specialties: General Dermatology, Otolaryngology, Plastic Surgery, Surgical Oncology, Radiation Oncology, and Oral and Maxillofacial Surgery. Mohs surgeons were most likely to use CCPDMA for tumors meeting NCCN criteria with 14/15 using this technique in a majority of their cases, versus 2/6 pathologists and 10/16 specialists from other fields. Reasons cited for not using CCPDMA included deference to pathologists to determine the appropriate method for margin assessment and logistical difficulty. CONCLUSION: Further efforts are needed to increase adherence to NCCN's guidelines regarding CCPDMA in KCs.

RESUMEN

Mycosis fungoides, the most common cutaneous T-cell lymphoma, is known to exhibit varied clinical presentations and mimic many other dermatoses. This morphological heterogeneity can often lead to initial misdiagnoses resulting in significant delays from symptom onset to diagnosis. We report a case of mycosis fungoides imitating clinical and histopathological features of erythema annulare centrifugum.

RESUMEN

INTRODUCTION: Psoriasis patients demonstrate high interest in the role of diet on their skin condition. However, data are lacking to describe dietary interventions among psoriasis patients and associated outcomes. This study aims to identify common dietary habits, interventions and perceptions among patients with psoriasis, and to examine patient-reported skin outcomes in response to these interventions. METHODS: We administered a 61-question survey to the National Psoriasis Foundation membership asking psoriasis patients about dietary habits, modifications, skin responses, and perceptions. RESULTS: A total of 1206 psoriasis patients responded to the survey. Compared to age- and sex-matched controls, psoriasis patients consumed significantly less sugar, whole grain fiber, dairy, and calcium (p < 0.001), while consuming more fruits, vegetables, and legumes (p < 0.01). Eighty-six percent of respondents reported use of a dietary modification. The percentage of patients reporting skin improvement was greatest after reducing alcohol (53.8%), gluten (53.4%), nightshades (52.1%), and after adding fish oil/omega-3 (44.6%), vegetables (42.5%), and oral vitamin D (41%). Specific diets with the most patients reporting a favorable skin response were Pagano (72.2%), vegan (70%), and Paleolithic (68.9%). Additionally, 41.8% of psoriasis respondents reported that a motivation for attempting dietary changes was to improve overall health. CONCLUSION: This national survey is among the first to report the dietary behaviors of patients with psoriasis. The data provided from this large cohort may benefit patients and clinicians as they discuss the role of diet in managing both psoriasis and associated cardiometabolic comorbidities.

RESUMEN

BACKGROUND: Patients with atopic dermatitis (AD) commonly turn to dietary modifications to manage their skin condition. OBJECTIVES: To investigate patient-reported outcomes and perceptions regarding the role of diet in AD. METHODS: One hundred and sixty nine AD patients were surveyed in this cross-sectional study. The 61-question survey asked about dietary modifications, perceptions and outcomes. RESULTS: Eighty seven percent of participants reported a trial of dietary exclusion. The most common were junk foods (68%), dairy (49.7%) and gluten (49%). The best improvement in skin was reported when removing white flour products (37 of 69, 53.6%), gluten (37 of 72, 51.4%) and nightshades (18 of 35, 51.4%). 79.9% of participants reported adding items to their diet. The most common were vegetables (62.2%), fish oil (59.3%) and fruits (57.8%). The best improvement in skin was noted when adding vegetables (40 of 84, 47.6%), organic foods (17 of 43, 39.5%) and fish oil (28 of 80, 35%). Although 93.5% of patients believed it was important that physicians discuss with them the role of diet in managing skin disease, only 32.5% had consulted their dermatologist. CONCLUSIONS: Since dietary modifications are extremely common, the role of diet in AD and potential nutritional benefits and risks need to be properly discussed with patients.

RESUMEN

INTRODUCTION: Chronic skin conditions have been well reported to affect a patient's quality of life on multiple dimensions, including the psychosocial domain. Psychosocial is defined as the interrelation of social factors with an individual's thoughts and behavior. The assessment of the psychosocial impact of skin disease on a patient can help direct the dermatologists' treatment goals. To evaluate the psychosocial impact of skin disease, we conducted a review of the literature on three skin conditions with onsets at various stages of life: acne, vitiligo, and psoriasis. METHODS: A PubMed search was conducted in March 2015 using the terms "psychosocial" AND "acne", "psychosocial" AND "vitiligo", and "psychosocial" AND "psoriasis". The results were limited to articles published in English in the past 5 years studying patients of all ages. Results and their references were evaluated for relevance according to their discussion of psychosocial qualities in their patients and the validity of psychosocial assessments. The search for acne yielded 51 results, and eleven were found to be relevant; vitiligo yielded 30 results with ten found to be relevant; and psoriasis yielded 70 results with seven found to be relevant. RESULTS: According to the articles evaluated, 19.2% of adolescent patients with acne were affected in their personal and social lives. Social phobia was present in 45% of patients with acne compared to 18% of control subjects. Race and sex played a role in self-consciousness and social perceptions of the disease. Vitiligo negatively affected marriage potential and caused relationship problems in >50% of patients. Psoriasis negatively affected multiple domains of life, including work, relationships, and social activities. Anxiety and depression affected not only psoriasis patients but also their cohabitants; up to 88% of cohabitants had an impaired quality of life. CONCLUSION: Though all three skin conditions resulted in an increase in anxiety and depression among their patient populations, the psychosocial focus varied slightly for each disease. Overall, acne, vitiligo, and psoriasis can have negative psychosocial impact in different stages of life development.

RESUMEN

A common therapeutic modality for psoriasis includes the combination of phototherapy with topical treatments. The recent development of targeted phototherapy with the excimer laser and spray formulations for topical treatments has increased the efficacy and convenience of these combinational therapies. Herein, we aim to assess the efficacy of a novel combination of therapies using the 308 nm excimer laser, clobetasol propionate spray and calcitriol ointment for the treatment of moderate to severe generalized psoriasis. In this 12-week study, patients with moderate to severe psoriasis received twice weekly treatments with a 308-nm excimer laser combined with clobetasol proprionate twice daily for a month followed by calcitriol ointment twice daily for the next month. Of the 30 patients enrolled, 83% of patients (25/30) achieved PASI-75 [65-94%, 95% confidence interval (CI)] at week 12. For PGA, there was an estimated decrease of 3.6 points (3.1-4.1, 95% CI, p < 0.0005) by week 12. In conclusion, the combination of excimer laser with alternating clobetasol and calcitriol application has shown to be a promising combination of therapies for the treatment of moderate to severe generalized psoriasis. Further evaluation may be conducted with a larger study inclusive of control groups and head-to-head comparisons against topical steroid and UVB therapy as monotherapies.
